How to know if the GBasis has already been computed? there is a member flag (myGBasisIsValid), but we should have a function (also in cocoa5): sometimes we could have different strategies depending on whether a GBasis is known or not.

I implemented it.
It took a remarkably long time mostly for choosing the name and deciding where to put it.
In fact this could be HasTidyGens
in the abstract class ideal
.

Even though I invented it, I do not much like the name TidyGens
...
Also, it is not clear to me how to deal with the situation where an ideal might have both a GBasis and a JBasis (or even a Pommaret basis); what should TidyGens
produce in such a case?
